The 'Site' monitoring service, which tracks Islamist militant statements, said that an Islamist militant group called the Turkistan Islamic Party (TIP) had claimed responsibility for the bomb attack at the Urumqi train station in late April that killed one person and injured 79. According to 'Site' on 11 May the TIP  released a 10-minute video in the Uighur language showing the construction of a briefcase bomb which it said had been used in the attack. The video was produced by the TIP's Islam Awazi Media Centre.
